SWINGING-SASH-FRAME FASTENER.

Specification of Letters Patent.

Patented Apr. 11, 1916.

Application filed March 1, 1915. Serial No. 11,407.

To all whom it may concern:

Be it known that I, CASPER FAUs'r, a citizen of the United States, and resident of Oshkosh, in the county of Winnebago and State of Wisconsin, have invented certain new and useful Improvements in Swinging-Sash-Frame Fasteners; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention refers to horizontally swinging sash-frames, which sash-frames may be inlaid for windows, screens, hot-beds or the The object of my invention is to provide a simple, economical and effective fastening mechanism for securing the sash-frame in various open positions with relation to its carrying frame and for fastening the said sash-frame in its closed position.

With the above object in view the invention consists in certain peculiarities of construction as set forth hereinafter with reference to the accompanying illustrations and subsequently claimed.

In the drawings Figure 1 represents a fragmentary view of a frame and sash equipped with a fastening mechanism embodying the features of my invention, parts being broken away and in section to more clearly show certain details of construction; Fig. 2, a plan view of the same; Fig. 3, an enlarged detailed sectional view of a joint embodying one of the features of my invention, the section being indicated by line 3-3 of Fig. 1; Fig. 4, a similar section View of the joint, the view being taken upon a plane indicated by line 44 of Fig. 1; Fig. 5, an enlarged side elevation of the assembled joint with the manipulating lever connection in section, and Fig. 6, a similar view of a modified form of the joint with parts in section to more clearly show the internal construction.

Referring by characters to the drawings, A represents a window frame having an inclined bottom rail A of the ordinary construction, and B a vertically swinging sashframe which is adapted to form a closure for the window frame A, the said sash-frame in Figs. 1 and 2 of the drawings, being shown open to form a vent and is, in this exemplification, especially arranged as a storm window.

1 represents a metallic bracket which is anchored to the lower rail of the window frame by a screw 2, the said bracket having legs 1 which are of unequal length to compensate for the inclineof the loWer rail,

whereby the upper face of the lower bracket is positioned upon a horizontal plane. The reta nlng screw 2, in this exemplification of my nvention, serves also as a pivot-bolt for the inner end of a strap 3, which strap is arranged to swing upon a horizontal plane or at a rlght-angle to the swing of the sashframe.

The free end of the sash-frame B carries a pm 4, which engages the eyed end of a strap member 3. strap member, is formed with a head 5,

the lower face of which is provided with a series of radially disposed V-shaped teeth 5 which constitute clutch members that lntermesh with a corresponding toothed face 6 of a head 6, with which the end of the strap 3 is provided. Both of the strap heads are formed with central apertures through which a retaining stud 7 passes and, as best shown in Figs. 4 and 5, the lower end of the stud is headed, while the upper end 1s passed through an aperture in the hub 8 of a lever 8, the said stud being upset therein. The lower face of the .hub 8 is provided with a screw element in the form of cam surfaces 8", which cam surfaces seat upon corresponding cam surfaces 5 of the strap head 5.

By this construction it will be observed that when it is desired to lock the sash-frame at the extreme position shown in Figs. 1 and 2, or at any intermediate or fully closed position, the locking lever 8 is twisted so as to cause the hub to rise due to the engaged cam faces. This rise of the hub will draw the headed stud 7 upward, whereby the V- shaped clutch-teeth will be securely bound together to thus firmly lock the joint irrespective of the angle assumed by the strap members.

To unlock the joint, a slight reverse movement of the lever 8 will cause its hub to drop downwardly to the positionshown in Fig. 5, whereby the teeth of the clutch heads will be free to disengage each other and thus the sash-frame may be moved freely in or out, the joint connection therebetween permitting such movement.

It is also manifest that when the window is drawn in tightly to its seat with relation to the window-frame A, it can be locked in this position by a slight twist movement of the lever previously mentioned,

The opposite end of this whereby the jointed clutch-heads are tightly drawn together.

Particular attention is called to the fact that the serrations or teeth are of sufficient number to permit fine adjustment from closed to full open position of the sashframe and when so adjusted and locked there is no liability of the joint becoming loose except through a positive movement of the lever A. It is obvious that in place of the lever or crank A, a wheel or knurled head may be substituted therefor, but it is preferable to use a lever construction for the reason that these fittings are usually manipulated by women or children and hence, owing to the lever construction, slight power is required to effect the desired release and lock of the parts.

Fig. 6 shows a modified form of clutch connection for the strap elements, wherein the lever 8 terminates with a flat-faced head 10, from which head there is extended a stud 10 that is threaded at its lower end for engagement with, a correspondingly threaded aperture 10 in the lower head 6, it being understood that in this case both the heads 5 and 6 are formed with the clutch teeth previously mentioned. Hence it will be seen by this construction that when the lever is operated in one direction it will permit the threaded engagement between the stud and aperture 10 to free the clutch teeth or bind the same when operated in the opposite direction. This construction eliminates upsetting as would be required wherein the threaded elements or cam faces are employed, as shown in Figs. 1 to 41; inclusive.

I claim:

In a swinging sash frame fastener, the combination of a pair of links connected for angular adjustment means for securing the outer end of one link to a sash and means for securing the outer end of the other link to a window frame comprising a plate having its side edges bent laterally to provide supporting means whereby it may be held spaced above the frame,- and a securing member passed through the link and through the plate and engageable in the frame.

In testimony that I claim the foregoing I have hereunto set my hand at Oshkosh in the county of lvinnebago and State of Wisconsin in the presence of two witnesses.

CASPER FAUST.
